Greenheck’s Indoor Air Handling Series, models MSCF, LFC and VFC, provide air conditioning and/or heating for buildings and specific spaces. The series was designed with low-profile construction to fit within tight spaces in applications such as schools, office buildings, apartments, medical facilities and many other commercial applications. Each model has a variety of sizes and a wide performance range with quiet, trouble-free operation.
Modular Indoor Air Handler Model MSCF-FC Model MSCF-BI
Modular construction allows the design engineer to configure a unit to meet their exact requirements. The modular construction also makes the MSCF ideal for retrofit applications. (See pages 5 thru 9 for more information.)
Vertical Fan Coil Model VFC-FC Model VFCD-FC
A vertical fan coil unit, all-in-one construction, is ideal for providing cooling and/or heating for applications requiring a small footprint. (See pages 12 thru 15 for more information.)
Horizontal Fan CoilModel LFC-FC
A horizontal fan coil unit is ideal for price sensitive applications. The LFC, all-in-one construction, results in a shorter unit which is ideal for space constrained applications. (See pages 10 and 11 for more information.)

Low-Profile — Every model has been designed as a space saving alternative to other products on the market. The height of each unit will be 4 to 8 inches less than any competitor model.
Internal Isolation — Internal neoprene isolation and flexible blower to housing connection is standard on every unit. This isolation improves longevity of the unit and reduces the potential of noise and vibration generated from fan vibration that could be transmitted to the attaching ductwork. Internal spring isolation is also available on all VFC sizes and on MSCF and LFC sizes 20 thru 85.
Greenheck’s Indoor Air Handling products have been designed with superior quality and come standard with premium features that make it ideal for any installation.
Side Access Panels — Units are constructed with easily removable access panels. Panels are formed and positioned on both sides of every module or unit to provide extra rigidity and help maintain cabinet pressure.
One-Inch Double-Wall — Double-wall construction on all units provides excellent indoor air quality as well as improved radiated sound characteristics over traditional single wall and exposed insulation models.
Model Number Code(s)
Standard Features and Benefits
Drain Pan — The double-wall constructed insulated stainless steel drain pan utilizes a double pitch slope directing condensation to a main or auxiliary drain connection. The pan improves indoor air quality by preventing the growth of mold and bacteria. The drain pan removes easily for coil cleaning.

Mixing Box — The mixing box module can be configured using any of the three inlet connections (top, bottom and inline or inline, right and left) and three damper styles (“V” blades, low leakage, and airfoil low leakage). The mixing box can also be configured with a filter to reduce overall unit length.
Disconnect Switch — An optional NEMA-1 disconnect switch is available. The J-box is mounted and wired at the factory. The switch is installed in the field.
Filters — Vertical or sloped filters are available depending on model. Filter efficiency selections include: 30% MERV 8, 65% MERV 11, 95% MERV 15.
Control Center — This control center is equipped with a 24-volt starter, transformer, and terminal strip all mounted in a NEMA-1 enclosure. Standard features include an interlocking door disconnect switch and an adjustable electronic thermal overload. This reliable control center reduces installation time, ensures safety and decreases demand on panel space. The control center is UL Listed for Safety for Industrial Control Panels, UL 508A.
Dimensions are 14 x 8.5 x 6.5 inches (355.6 x 215.9 x 165.1 mm) (L x W x H)
Fan Types —• Forward-Curved — Double-width, double-inlet
forward-curved blowers are designed to efficiently move high volumes of air with low sound levels. Available on all models and sizes.
• Backward-Inclined — A backward-inclined plenum fan is available on the MSCF. Backward-inclined fans are ideal for high-pressure applications across the entire CFM range. Available on MSCF sizes 25 thru 85.

What's This…Each MSCF modular section maintains
its own access panel providing excellent
accessibility to all components. All panels
have formed edges, which provide additional
rigidity and enables the MSCF to maintain
cabinet pressure.

What's This…Belt drive fans offer the ability to adjust
fan speed for system balancing if
necessary. They also offer more flexibility
in speed and motor selections than direct
drive fans.
